I know it's not an arcade monitor but i picked up a 19 inch sony tv for $20
Looks pretty good. It has capacitor isues like the audio will die completely after a few minutes.
(made in 1992 sony kv-19ts20)

I left it in a cold storage room not freezing but very cold pulled it out sounded like the flyback was arcing tried it a second time same deal.
Then i let it warm up to room temperature and it works no arc.

what is that a sign of?
 
Dust on the tube surface collected condensation from the temperature change, HV was able to arc its way through the moisture to ground. Let electronics dry out before applying power.
